T 0 all whom it may concern:-

Be it known that I, Hueo KEITEL, a sub ject of the German Emperor, residing at Dusseldorf, Germany, have invented new and useful Improvements in Carbureting Apparatus, of which the following is a specification.

The subject of the present invention,'is an apparatus for the production of carbureted air from liquid hydrocarbon and air, and is thereby characterized, that there are two gasolneters, of wlnch one measures off a stated and always equal uantity of air, and

actuates a distributer an a vat or reservoir for measuring off the hydrocarbon, while i the second gasometer stores up the generated 'carbureted air and contains in its basin a carburetcr in the form of a helical tube the top-bell of which, when there is a sufficient supply of carbureted air, causing the distributing mechanism to come into action, '1". -e., it stops the working of the apparatus when the carbureted air is no longer required. The accompanying drawing shows in Figure 1, a mode of construction of the ap )aratus, in longitudinal section and part y in front elevation, and in Fig. 2 a section in the direct-ion of the line A-B of Fig. l.

n )rinciple the. apparatus consists of a helical tube, 2 constituting the carbureter, built into the basin of the gasometer 1, and of a reservoir, for the measuring off of a certain volume of air, formed of a basin or tank 3 filled with a blocking fluid and a top-bell 4, and the reservoir 5 for the liquid hydrocarbon. This reservoir 5 is intended to act as a supply for a large quantity of the liquid hydrocarbon, so that it is capable of receiving the whole contents of a barrel. In the reservoir 5 there is used a scoop 6, which is chamfcrcd Connected by a rope 7 with a winder 31 which dips the scoop gently into the hydrocarbon and as gently raises it, in order to avoid ripples which would otherwise be caused by the cold occasioned by vaporization. In the case of the construction shown in the drawing, the winder is actuated by the top-bell 4, the connection being effected by the rope T. The scoop 6 and the stirrup and bolt which fastens the rope or other similar contrivance 7, and guided between angle rails or upright guides 8, so that the scoop can neither turn swing nor otherwise move out of the perpendicular. The outlet or spout of the scoop is and engages, on being raised,

over the stop-block 9. As a consequence of out of H5 more or less perpendicular position into the horizontal, -so that the carburetin fluid is ripped into the grooved guide 10, an

runs from thence into the pipe 11, which discharges below the upper turn in the carbureter 2. There is a screw provided against which the scoop strikes this screw passes through the wall of the reservoir 5 and turns in 12. If this screw is raised or lowered, the

scoop delivers more or less of the hydrocarbon. If desired, a scale may be arranged on or beside the screw, whereby it could readily beaseertained what quantity of fluid the scoop delivered at each operation. Instead of the adjusting screw, an adjusting ushrod or other similar contrivance con (1 be employed, and it is not essential that the screw itself should form the block or stop,

striking this stop-block, the scoop is brought on being tipped the threaded part but may be employed for adjustingthe block only. 7

The air is carried to the aerometer or the top-bell 4, through the tubes 15 and 16 to which must be coupled the tube 17 leading to the carbureter. The air is compressed by a compressor in the housing 14, and the compressor nia y be an air pump, Roots blower, or it may be worked by weights or hydraulic power. Between the tubes 17, 16 and 15, there is a three-way tap 28 which is so actuated by the top-bell 4, that when the latter is raised, the lead 16 is connected with the lead 17 and when it is depressed, the lead 16 is connected with the lead 15. On the topbell 4, there is attached a carrier 18 which actuates an overbalanced tilting lever 19, which is placed in front of the cone of the three-way tap. When the top-bell 4 moves downws-ds as shown, the carrier takes the tilting Beyer 19 into the position shown by the broken lines, 11. 2. over the perpendicular, so that. finally, it tilts over to the other side. It then engages with a in 23 which is in the disk 20 which is attac red to the tap-cone, thus bringing the tube 16 suddenly out of connection with the tube 17 and, at the same time, sea ring up the connection with the tube 15. On the top-bell being raised through the agency of the inrushing air, the carrier 18 strikes against the other weighted arm of the tilting lever and moves it by pushing forward the somewhat pointed weight until it slips orer and strikes against the other of the the pipe 15 is suddenly interrupted and the pipes 16 and 17 again putinto connection with each other. At every rise and fall, 1'. e. at every filling and emptying of the top-bell 4 5 the scoop, which is connected by the rope &c. 7 is raised and lowered and, "consequently, filled and emptied. In the rope &c., 7*

7 there is an interpolated s 'ring 30 which, when the screw is turned own so far that 10 the screw strikes it before the bell is C0111- pletely raised, permits it to go further on its upward travel. For the case when, on account .of the carbureted air being no longer required or only a small uantity is being drawn oil", the top-bell of t 1e gasometer has risen only to a certain point, the supply of air to the aerometer 4 or to the carbureter 2,

is automatically interrupted. "F or the interruption of the carbureting process, there is a two-armed lever 24 which is actuated by the to -bell of the gasometer, which, when the be I has risen to acertain point, engages with a lateral catch or stud over. a finger 25 of the -disk 20 and thus prevents its turning and 25 setting up the connection of the pipes 16 and 15.

\ The air under pressure which is always ex- \act1y measured by the top-bell 4 and driven into the carbureter 2 and which has a correct ratio to the contents of the scoop, ascends within the carbureter coil and here meets the hydrocarbon delivered by pipe 11 and slowly descending within said coil. As the distance which the two components of the carbureted air have to travel in opposite directions is considerable and as, in consequence of the helical form a certain whirling motion is set up, but especially of the air, the hydrocarbon is completely absorbed and, as the hydrocarbon and the air are mixed in carefully measured quantities and the velocity of the an employed in the helical carbureter' remains the same, no matter whether a large or small quantity of carbureted air is being drawn oil, the latter always contains the same components in their correct ratios.

As the hydrocarbon is fed underneath the upper turn or turns of the carbureter, a union of this component with the finished product under the top-bell and a consequent absorption independent of the fresh compressed air,

is prevented. The blocking liquid for the meter bell 1, serves, at the same time, to prevent a too sudden cooling of the pipes of the carbureter. As a suitable liquid, we take under C. (cold) and which is fire proof. In order that there is a good and constant circulation of the li uid, and that,'instead of that which is cooler by the ipes of the carbureter other, warmer liquit comes to take its place, there are legs, knives or other similar. contrivances placed on the inside wall of the top-bell; the carburetor is, besides this, arranged in a hollow cylinder 27 which is perforated as at 29. Through the rising and falling of the top-bell, the knives 26 or similar contrivauces stir up theli uid, while, the hollow cylinder 27, in itself, rings about a natural circulation, in that the specific gravity of the blocking fluid in the hollow cylinder has been heightened by the cold occasioned by evaporation in the helical carbureter, causing it to sink and leave the cylinder 27 by the holes 29 when the legs or knives catch it and churn it round. The top-edge of the hollow cylinder is lower than the surface of the blocking fluid, so that the warmer ortion and, consec uently, the lighter, circuates round the car ureter, keeping it always at nearly the same temperature.

I claim:

1. A device of the character described, com arising a tank adapted to contain a. blocking liquid, an air bell telescoped by the tank, an air compressor, a carburcter, a gasometer bell conununicating therewith, a three-way cock, means controlled by the air bell for. setting said cock to establish alternate communication between air bell and compressor and between air bell and carbu reter, and means controlled by the. gasometer bell for locking the three-way cock, substan tially as specified.

2. In a device of the character described, a. gasometer having a bell and adapted to contain a blocking liquid, a carburcter Within the gasometer, and stirrers on the gasometerbell for agitating the blocking liquid, substantially as specified.
